R33 Popping / Cracking Exhaust Noise.

[r32-25t]

sounds legit, becuase i rang castle hill exhaust and the quoted me $950 for a 3'' Mandrel bent (Mild steel/stainless cannon) with 100cell

hi flow cat. you think this would be suitable for my setup or should i go 3.5 for when i do more work? i just dont want the drone like you mentioned and i dont want to loose back pressure

why don't you want to lose back pressure thru in the exhaust? The idea in a turbo charged car is to make sure the exhaust doesn't have back pressure
